Every good love story has another love hiding within it. Brokenhearted, still mourning the loss of her husband, Heidi travels with Abbott, her troubled eight-year-old son, and Charlotte, her intolerably jaded sixteen-year-old niece, to spend the summer repairing their family home in a small village in the south of France. The rundown stone house in Provence has been in the family for generations and is the centre of a lovely myth. The family tells and retells stories of the magical properties entwined around the old stones - in many different ways, this house has healed broken hearts and made miracles happen. There, thousands of miles from home, Charlotte makes a shocking confession, and Heidi learns the truth about her mother's 'lost summer' -- a time Heidi and her sister had learned not to ask about many years ago.
